You probably don't need flashlights too often, but when a power outage occurs or you're outside at night they're certainly useful. Solar flashlights are a better option, too, because you can just leave them by the window and never have to worry about the batteries. With this DIY option, you definitely don't have to worry because it doesn't require any batteries at all.

Of course, you need to be able to store energy somehow. While most solar-powered flashlights store energy in batteries, this DIY project saves it directly in two one-farad super capacitors. This simple project is not only practical for those times you need a flashlight but also to learn about solar energy storage. If you watch the video above, which details each step, you'll see it's aimed at kids and is something most anyone can accomplish with the right tools and components.
